Rocket oven from steel drums - a lenghtier option

Hi, all.

I am at the beginning of making another rocket oven which has a longer oven inside. The original size that was introduced in Rocket Ovens DVD was abit short for our summer camps. Now i will make one that has 60cm (24") long compartment so that i can bake three pans that are 50cm (20") long.
Since the volume to be heated is larger and since the volume of baked food is larger i am thinking of coupling it to a larger J-tube system, probably 175mm (7"). Thoughts about that are welcome.

Yesterday i opened two drums. In the next days i will start making it..

Oh, some photos of my previous oven can be seen here:

And final appearance with metal sheet cover:




Have a nice day,

Soo, the new Rocket Oven with a lengthier inside and more powerful J-tube has been in use for two weeks of our Forrest Department Camps (you can see a sexy video of camps here www.gozdnioddelek.si, but site is not in English). If i compare it to last year (original version) of Rocket Oven, this one can bake much more food with much less fiddling of tiny twigs of firewood. Last year if i wanted to achieve the right temperatures with plenty of food baking inside, i had quite a  hard time adding lots of small twigs and pieces of wood (more burning surface in a moment gives more power)...This year this is soo much easier - I'M LOVIN' IT! This is the piece of camp kitchen i have been looking for!

Below are the photos of construction - the working oven will be in the following photos...

Hi, people!

I will be designing Rocket oven from sheet metal - another larger version where i can accept 65x53cm trays (GN2/1). All the details will be available on the donkey32 forum:

Quick sketch (door are not sketched yet)


My previous (second one) lenghtier rocket oven that i made with steel drums performed very well for two years but now i need a larger one...
I do have a question regarding what burner should i use -i posted that in a donkey32 form that i posted a link just above.

Have a nice day,
